Maintenance (test of the overtemperature shutdown and temperature check-up see 13.2. and 13.3) should be
carried out regularly to detect possible technical failures.
The electric fuses are placed at the back of the device between the power switch and the mains plug. After pulling
off the mains plugs and pushing upwards a safety catch the fuses can be changed. Use only fuses with correct
values (indications about the fuse type are placed at the back of the device).
The device may only be opened by a qualified specialist. Unauthorized work on the device voids the warranty. All
kinds of repairs may only be carried out by authorized persons using original replacement parts.
The replacement of single components of the device must not be done by the user but exclusively by authorized
specialists. Therefore the device must be sent to the manufacturer. The surface of the device should be
decontaminated with a lint free cloth soaked with 70 % ethanol before sending. The drill holes of the thermoblock decontaminated with a lint free cloth soaked with 70 % ethanol before sending. decontaminated with a lint free cloth soaked with 70 % ethanol before sending. decontaminated with a lint free cloth soaked with 70 % ethanol before sending.

13.2 Test of the overtemperature protection
A periodical test of the overtemperature protection is recommended (see chapter 12.6.1).
13.3 Temperature check-up
Maintenance of the temperature at regular intervals is recommended. The thermometer for use should be equipped
with wired sensing devices (e.g. Pt1000) and should have an accuracy of measurements of 1/10 class B (∆T =
±0.03 °C) in the range of 0 to 100 °C. While processing the temperature control the room temperature should be
25 °C at maximum.
13.4 Calibration
If there is a reasonable suspicion that the device has deviated from the calibration range, because the variations of
the temperature check-up are considerably out of the acceptable tolerance, a new calibration must be carried out
by the manufacturer. Please contact your local distributor.
14 WARRANTY
The period of warranty for the product at hand is 24 month from date of purchase. The warranty does not apply
for defects caused by incorrect, improper or inappropriate use. The customer has to check up on obvious defects
promptly upon receipt of the device and send a written report. Otherwise the claim for warranty expires. The
